' Be it known Athat I, Animar H. Born, a citi- .zen of the United States 'of America, residmg at Leadville, county of Lake, and State Valve, of which.

My inventlon relates to improvements in valves, and the-objects of my invention are: First, tourovide an automatic quick closing valve. econd, to provide an automatic Sprin controlled instantaneous closing valve. And t ird, to provide a distributing and cutoil' valve that is adapted to 'be used for steam generating and steam distributing ya manuall operating that can be closed from any predetermined by any one in the vicinity in case a steam pipe or joint1 bursts or breaks. I attain these objects by the mechanism illustrated in the accompanying drawings, in which:

Fig. 2 is a down or upon its seat, the spring which holds the auxiliary valve stem up being drawnto one side, permittingtheexpansion spring to throwA the stem down.` Fig. 3, is a yertlcal, longitudinal sectional view, show- 1n my invention applied to 'a screw cap va ve.` And Fi .4, 1s a rs ective View of the auxiliary va ve s mol mg spring.

I collar 8, which is adapted to b ear against the nut 9, that forms the top part of the valve disk 7, The valve disk 7, which may be of any suitable construction to lit the valve seat, is provided with an auxiliary valve stem l0, which is connected to it in a suitable manner but preferably by a socket `oint, which i's made as follows: The valve disk is provided with a.hollow chamber 11, the entrance to which is closed by the nut 9, which 1s provided with a short extensionthat is threaded into it, and the lower end of the stem is provided with a head portion 12, which lits loosely in the'chamber of the disk, While the nut. 1s provided with a smaller a erture than the chamber, through which t e stem of the valve disk extends loosely. The auxiliary valve stem is formed in two diameters, at the' junction of which a shoulder 13, is formed. A coiled sprin 14, is mounted' on thesmallest diameter o the stem, thel lower end of which bears against the shoulder 13, which formsian abutment fpr it. *1I-"he .common or main valve stem 4, ifs. rovided with an axial aperture 15, which is a so made inl two diameters, that are ada ted to receive slidably the two diameters o the auxiliary valve disk stem, and the spring 14, the u'pr end of which bears vagainst the shoulder gdrmed at the junction o the two apertures 1n the common valve stem, the larger aperture fv which is extended into thevalve stem far enough to extend over the spring when at its normal extended length, and to form an abutment shoulder for its upper end. The auxiliary valve diskstem is made long enough-to extend through and beyond'the main stem a short distance, which 1s a 11ttle greater than the travel of the valveldlsk to .and from its seat, and close to the end of the stem I form an annular circumferential-recess 16, which forms a reduced in the stem. The hand wheel of the valve stem is keyedor otherwise secured to the mam stem ata short distance from its end, while the yend'offthe stem is threaded and a packing nut 18,is threaded to it. This nut contains a central aperture throughwhich'the auxillarf. stem extends, and this nut 18, is used to pac 'the auxilia stem. To the main vsteml or to,

neck portion wheel, I secure one end o a blade sprin 19,

The common valve stem,- which is threaded; 4fthe opposite end of which is'bent at" right and-which is normally connecte to the va ve disk, is separated fromit inA my; invention, and its lower end is provided 'wit l angles to the body of 'the stem towards the.'

stemand contains an oblong slot. 20, which' fits loosely over the endl of the'stem and is resiliently positioned 'relative to lthe reduced neck portion of the stem so that the nearest sidel of the slot to the blade of the spring will normally bear resiliently in the recess 16 and against the neck. The auxiliary stem is thusreleasably lockedl to the hand wheel, and to the main valve stem, and normally' is moved to open and close the valve disk to and from` the valve seat, when the hand wheel is turned to either o en or close the valve. To .the upper end of t e sprinv ,I secure one end of a cord or of several cor 21, the op osite end4 of which is extended to any pre eter 4mined point or to different points in a mine or factory.

The operation is as follows: The auxiliary stem is pulled upthrough the main vstern until the top of the valve disk rests against the bottom of the collar 8, on the end of the' main stem, in which position .the edge of tie slot of the spring 19, will spring resilient y into the recess 16, against the neck of the stem, and lock the stem to the` wheel, and when theauxiliary stem is pulled up, the spring 14, is compressed against the shoulder 1n the main stem so that when the stem is locked to the hand wheel b the blade spring,

, however, a ,steam pipe or fitting or joint bursts or breaks, andsteainescapes, as for instance in the bottoniof a mining shaft or tunnel,\to which one or several cords may lead, or to the different levels of a shaft or to different floorsrfo a facto `or manufacturlng plant, a long distance rom the boiler or boilers, any person can grasp the cord and by pulling it pull the spring out of engag'ement with the stem, which releases the aux1l1ary stem, and the spring 14, instantly throws the valve disk down von its seat, and closes the valve. Then after the break is fixed, the valve disk is again locked to the hand wheel by lifting it and locking the blade sprmg in the neck ofthe stem.

My invention is simple, practical, not liable to get out of order, and places at the hands of workmen or employers a means of quickly shutting off steam at the steam generating lant from any one or from a number of dlerent points at long distances from the steam generating plant. Having Idescribed my invention, what I claim as new and desire to secure by Letters Patent, is:
